摘要
为了满足实验室研究风力发电技术的需要,该文设计了动态风力机模拟器。在分析实际风力机与模拟系统差异的基础上,综合考虑了风力机的风剪效应、塔影效应及其风力机的大惯量特性,提出了转矩指令动态补偿的转矩模拟方案。详细分析了惯量补偿的原理,并对其正确性进行了数学论证。理论分析和仿真结果表明,模拟系统的动特性与风力机的理论动特性高度吻合,可方便地用于实验室条件下的风力发电技术研究。
To meet the demand of studying wind generation technology in the laboratory, a dynamic wind turbine simulator was designed. Based on the analysis of the differences between actual and simulation system, a novel dynamic torque compensation scheme was developed, which considered wind shear effect, tower shadow effect and big inertia of the actu- al wind turbine. The principle of the inertia compensation was analyzed particularly and a mathematical argumentation was carried out to prove its correctness. Both the theoretical analysis and the simulation result indicate that the dynamic char- acteristics of simulation system are highly consistent with the theoretical dynamic characteristics of wind turbine, can be conveniently used in the study of wind power generation in laboratory.
